The efficiency and value of the 3LC-355M3-6 model become evident in drives that must operate steadily, economically and without unnecessary downtime. This 1000 rpm electric motor is designed for environments where long-term operating reliability, energy costs and service availability under real production conditions are closely monitored.
IE3 efficiency class for lower losses in continuous operation
The IE3 efficiency class is particularly valuable in applications where the motor runs under multi-shift load and every percentage point of savings affects the return on the solution. Super high efficiency supports lower consumption in both normal and loaded operation, which is appreciated by production-hall operators, technologists and drive designers. Combined with an output of 200 kW, the electric motor provides reserve capacity for stable equipment operation without unnecessary overheating.
Robust cast-iron frame for load, vibration and rigid mounting
The robust cast-iron frame helps maintain precise positioning in equipment exposed to long operating periods, vibration and mechanical stress. Reinforced cast-iron bearing shields and reinforced cast-iron feet improve support during installation and when transferring load into the machine frame. This solution is suitable for an asynchronous electric motor in lines where rigid geometry and long bearing-service life are required.
1000 rpm electric motor for technological systems with smooth power transmission
The rated speed of 990 rpm suits technological systems where a balanced relationship between torque and starting behaviour is important. Rated current △ 400V 346 A and rated current Y 690V 200.58 A simplify switchboard design and protection sizing. A noise level of 85 dB(A) is consistent with the robust industrial-drive segment, where continuous operation in demanding production halls is expected.
Starting and dynamics for large machines
A starting torque ratio of 1.8, breakdown torque ratio of 2 and starting current ratio of 6.8 help when designing a system with regard to starting under load. Rotor inertia of 11.596 kg/m² supports stable operation in equipment with a higher moment of inertia. DE bearing 6322-C3 and NDE bearing 6322-C3 are suitable for applications where precise support and long service intervals are important.
Industrial automation in heavily loaded drives
In industrial automation, this electric motor is used in assemblies where reliable operation must be combined with precise transfer of power to the mechanical section. The manufacturer’s experience builds on years of development in the motorisation of heavier-duty operations, which is beneficial when integrating new lines as well as replacing older drives. The 2-M63X1.5 cable glands simplify installation preparation in assemblies with robust power cabling.
This motor is suitable for 13 specific applications: utility-water pumping stations, main extraction fans, screw compressors, conveyor lines handling heavy material, mixers with continuous dosing, roller conveyors in metallurgy, aggregate crushers, granulation lines, briquetting presses, drum mixers, packaging machines for bulk mixtures, process blowers and pumping units in the energy sector.
355 mm frame and packaging prepared for service handling
The 355 mm frame size simplifies connection to existing structures in smaller factories as well as large operations. A package weight of 1643 kg and package dimensions of 1607*822*1161 mm are important when planning handling, storage and installation at the destination. For operation on 400/690 V networks, the motor is ready for projects where supply, mechanical mounting and service access must all be assessed together.
If you need a motor for continuous load, order 3LC-355M3-6 today so it is ready for installation without unnecessarily extending downtime.
A 1000 rpm electric motor with IE3 efficiency class is suitable for operations that want to reduce energy losses while maintaining stable performance over long-term duty.
